,1 Claim. 1

My present invention relates to an improved protective means for tellers cages of the type especially adapted for use in banksand other institutions where money is handled frequently and in 1arge quantities.

The protective means of my invention consists generally in electrical circuit arrangements whereby under the control of the teller circuits may be closed to pass a current through the person standing in front of the cage to shock the person, and to provide for the sounding of suitable alarms. The current applied through the person, having been determined to be a potential thief is suflicient only to shock the person and insufficient to cause bodily harm.

In the accompanying drawings I have illustrated an embodiment of my invention in which the parts are combined and arranged in accord with one mode I have devised for'the practical application of the principles of the invention; but it will be understood that changes and alterations are contemplated and may be made in these exemplifying drawings and structures, within the scope of my appended claim without departing from the principles of the invention.

Figure 1 is a perspective view at the front of a bank tellers cage or station, and depositors counter.

Figure 2 is a plan view showing a floor grill related to the depositors counter; and Figure 3 is a plan view of a floor grill related to an office door of a banking room.

Figure 3A is a detail plan view of a floor grill detached.

Figure 4 is a sectional view of the open floor switch; and Figure 5 is a similar view with the switch closed.

Figure 6 is a sectional view showing a drawer switch; and Figure 7 is a detail sectional view at line '!-1 of Fig. 6.

Figure 8 is a diagrammatic view of the electrical wiring and circuits of the protective system.

Referring now to the drawings where I have illustrated interior portions of a bank lobby that is equipped with the protective system an upright partition 2 is provided with a horizontally extending counter 4 for depositors, and the edge of the counter is provided with an electrical conductor or strip 6. Usual glass panels 8 are provided in the partition, and conventional openings 10 and I2 are shown in the panels, together with a set of chimes l4 mounted on the partition 2.

In the tile floor of the bank lobby, immediately in front of the wall openings I0 and I2, an inconspicuous electric grill I6 of conducting material is laid in the tiling; and as seen in Figs. 3 and 8, a door It! is shown opening into the lobby and provided with a knob 20.

A second floor grill 22, as an electrical conductor, is also laid in the tiling in front of the door, in position to be stood upon by a person desiring to open the door.

To activate the electrically operated appliances of the protective system I utilize the line wires 26 as a current source of the 110 v. type, and wires 28 and 38 are extended from these line wires to a transformer 32, a secondary winding of which supplies high tension current to the operating circuit; and a main floor switch 33 is provided in wire 28 for pedal control of the circuit by a bank teller, or other person.

A wire 34 extends from one side of the transformer 32 to the end bar I04 of the floor grill [6, and wire 38 connects the wire 34 to the counter conductor strip S. A wire 38 is extended from the bar [53 at the opposite end of the floor grill l6 back to the transformer, so that, with the circuit switch closed, a person standing on the grill IE will receive a shock from the circuit.

Wire 48 from wire 34 is connected to the grill 22, and wire 42 is connected to the door knob 20, in order that with switch 33 closed, a person standing upon grill 22 and handling the door knob 20 will thereby complete the operating circuit and receive the shock from the electric current.

One of the line wires 26 is connected to another transformer 44 for reducing the voltage to a 10 v. current which passes through wire 46 to a pedal switch 48; and a wire 50 connects this pedal switch with the chimes M, from which wires 52 and 54 lead to magnets 55 and 56 and thence through wires 51 and 58 back to the transformer 44.

Wire 60 provides 110 volt current to armatures 62 and 64 from whence the current may flow through wires 66 and 68 as to police signalization and bank protective signalization.

The floor switch generally designated as 38 may comprise a foot plunger 10 reciprocable in casing 12 against spring 14 to fulcrum lever 16 on post 18. A link on the lever 16 has a reduced neck 82 and a head 84 of tear-drop shape, and an extension bar 86 with a disk 88 thereon above the casing for return of the actuated plunger 10. Spring clips 90 are connected to wire 28 and bear against the neck and head as the device is actuated, the head being non-conductive and the neck conductive.

From the above description it will be apparent that with the various circuits normally open, should a thief or bandit appear at the tellers window, the teller may depress the plunger I to energize the grills I6 and 22, and the bandit ii touching the strip 6 will receive a shock, whereupon it is likely that he will be frightened and head for the door whereupon he will receive another shock as described above.

The floor grill I6 is formed with a rectangular shaped frame I00 having side bars IOI and I02 and end bars I03 and I04. The end bar I03 is integral with the side bars and the end bar I04 is insulated from the side bars by insulating tips;

I05 and I06.

The end bar I03 is provided with a tongue I01 having laterally disposed fingers 10.8 extended. therefrom and the fingers are provided with insulating tips I09 and H0, which insulate the tongue and fingers from parallel bars I I I and I I 2 extended frsm the endbar I04. The parallel bars III and H2 are also provided with laterallydisposed fingers H3 and H4, respectively; theextended ends of which are provided withinsulatingtips. I I5 and H6. The extended ends of the parallel bars III and H2 are also provided with insulating tips II! and H8. The end of the tongue I0! is provided with an insulating tip H8 and similar insulating tips I20 and IZI are provided on the ends of the side bars I 0! and I02. The elements extended from the end bar I04 are, therefore, insulated from the elements extended from the end bar I03 whereby with electric current supplied to the end bars by wires 38 and 34, the two sets of elements provide two electrodes and the foot of a person standing on the grill bridges the said electrodes.

Having thus fully described my invention what I claim as new and desire to secure by Letters Patent is:

In a burglar alarm, the combination which comprises a floor grill having a rectangular shaped frame having side and end bars with one of said end bars insulated from the frame, a tongue having spaced laterally disposed fingers extended inwardly from the end of the frame integral with the side bars, tips of insulating material on the ends of said fingers and on the extended end of said tongue, spaced parallel bars extended inwardly from the insulated end bar of the frame, said spaced parallel bars positioned to, engage the insulated tips of the fingers of the tongue, said spaced parallel bars having laterally disposed fingers extended outwardly from the outer surfaces thereof, insulating tips on the extended ends of the fingers of the said spaced parallel bars, the-said fingers of the spaced parallel bars being thereby insulated from the fingers of the tongue, a vertically disposed bank tellers window spaced from the said floor grill, a power source having a transformer, a circuit connected to a terminal of one side of the transformer and extended to the tongue of the grill, and a circuit connected to the other terminal of the same side of the transformer and extended to the parallel- REFERENCES CITED The following references are of record in the file of this patent:
